Why Plant Trees?

  • Trees renew our air supply by taking in carbon dioxide and producing oxygen.
  • The amount of oxygen produced by an acre of trees per year equals the amount consumed by about 18 people annually.
  • One tree produces nearly 260 pounds of oxygen each year.
  • One acre of trees removes up to 2.6 tons of carbon dioxide from the atmosphere each year.
  • Trees save energy and money! Strategically placed trees around homes and businesses can make buildings cooler in summer and stop winter winds, saving big money on heating and cooling costs!
  • Tree roots stabilize soil and help to prevent erosion.
  • Trees help filter particulates out of the air, greatly improving both urban and rural air quality!
  • Trees cut down on noise pollution by acting as sound barriers.
  • Trees provide food and shelter for wildlife.
  • Trees are the longest living organisms on earth!
  • Trees are beautiful! Some of the most aesthetically pleasing views include trees. Landscaping which includes trees can improve the look of your home or office building and even raise property values!

Five Steps to Proper Tree Planting

  1. Plant the right tree in the right place. Select species that are suitable for your soil and sunlight conditions.
  2. Prepare a weed free area for each seedling. Weed control can start as early as the fall before planting in the spring, and at least several weeks prior if planting in the fall.
  3. Dig a hole slightly deeper than the roots are long, and big enough so the roots can spread out in a natural position.
  4. Firmly pack soil around the roots to eliminate air pockets. Water after planting; do not fill the planting hole with water.
  5. Transplanted trees should receive at least 1 inch of water per week during the growing season for at least 2 to 3 years following planting. Remember to account for rainfall so you don't overwater your seedlings. Drip irrigation or soaker hoses are better than overhead sprinklers or watering cans.

The Value of Mulch

A tree's best friend, mulch insulates soil, retains moisture, keeps out weeds, prevents soil compaction, reduces lawnmower damage, and adds an aesthetic touch to a yard or street. Remove any grass within the mulch area, and area from 3 to 10 feet in diameter, depending on tree size. Pour wood chips or bark pieces 2 to 4 inches within the circle, but not touching the trunk.
